All Fluids for 1976 Ford 335

[FORD3351976]

New to me Ford industrial 335 tractor Model #CU221C, (1976?)
with loader 19-529 (730)
with backhoe 19-388 (750)
I am going to change all the fluids so I have service starting point.
I need help with which fluids to use as not to harm this tractor.
Some original recommendations no longer available?
I am located in WI but tractor will not be used in winter months.

Engine Anti Freeze_____________________
Engine Motor Oil_______________________
Hydraulic Oil__________________________
Transmission Oil_______________________
Rear End Oil __________________________
Power Steering Fluid___________________
Did I miss anything?
Quantities would be nice but I do have shop manuals on order
for all systems.
Sorry for long post, thanks for sharing your knowledge!

Welcome to TBN!

Engine antifreeze - at this point, Prestone mixed to your coldest weather specifications
Engine oil - a good grade diesel motor oil. Probably 15w40
All other oils - a hydraulic transmission oil from New Holland, Deere, Kubota, Cat, Tractor Supply, Napa can be used.
You may save a little money on your loader/backhoe and power steering by using AW68 hydraulic oil.

Is it a power shuttle (F/R on left of steering wheel and no clutch)?
Oops! If I was paying attention to your post, the model code tells me it is an 8x2, no PTO.

Engine oil w/filter 7.0 qts
Coolant 2.75 Gallons
Transmission/rear end 13.8 qts
PS 2.0 qts

I will find the loader/backhoe for you 730 loader/750 backhoe setup

 

[TractorTech]

730 system capacity 10.5 gallons plus 6.5 gallons for 750 backhoe, but unless you purge all the cylinders you won't need much more than about 8 or 9 gallons. Don't forget to change the filter on the loader lefthand upright on the bottom

Do you have a source for the this filter? Also possibly for the air filter? I have been having trouble finding these items. Thanks for the info and help!

Also, you have 1976? Date code should be something like 6B16B which would be 1976, February 16
